It monitors PCIe power; IE a GPU's PCIe EXT power connector.

Thanks for sharing this and clarifying how you did this


And yes I do still follow your post about your test machine and the results that you have provided in your post about the motherboard that you tested

How did you make it so you could monitor the amperage of the PCIe slots that is interesting

2000 hour update....well close enough...



Nothing to really report; no problems or revisions.....but I did have a board in it creating one hell of a load!! X9DAI with a pair of E5-2667 V2's @ 3.3GHz 8C 16T 130W CPU's with 512GB RAM. Memtesting had it pulling nicely on the 12V rail.....







...and that's just memtest... It kept the room warm!!

This is the most professional thing I have seen in very long time with put together parts and I can see from the hour meter that you use it quite a bit and if you have been following my ZD-987 switching power supply modifications

I personally think that you did a very good job and made it look very professional and very functional at the same time

I get some of inspiration from this post and what you have done here to solve a monitoring the computer system voltage and current and see if things are the way they should be of course my situation is a little bit different in the respect of I was having switching power supply failure after many hours of use and need a solution for this issue of mine because too buy another dual desoldering/soldering station is not cheap over $250.00 plus shipping and a month of waiting time unless I can find a seller in the USA which is not easy and more often than that it is more expensive than buying it from China

Another little finishing touch.....labels for the controls & lights. This isn't realy how I wanted to do it; the original plan was vinyls with my wife's cricut.....but that wasn't working at all with letters so small....so I ended up using the label maker. Yes, after a couple years, I know what everything is for.....but it just looked incomplete without some kind of labeling....so here it is.








Now you know what all the lights are for.....

I will add something to this as well you do have downloaded the firmware and make sure that your system recognizes the device I personally could not get the FireWire to work correctly but could get the USB 3 cable to work but you do have to get the USB 3 PIC card from them for it to work correctly on older systems and your system needs to recognize it as well in the device manager

If you have a computer that has USB 3 dose not necessarily mean that the device ( Windows 7 ) will be found I ran into this issue with an older system

I also have very new computer and it has no issues with finding the device and working correctly ( Windows 11 )

It will work with this USB 3 PIC card
https://www.ebay.com/itm/315216805876

I have bought several of them from this seller before

One way to tell if you device is working correctly see if you can read a USB thumb drive or not if you can it is working correctly

The issue I have is that is that I cannot use it to copy drives for some reason which I have not figured out exactly what the issue is

Hi there!
How do you connect the Tableau T3458is Forensic Bridge to the motherboard??
Is it necessary to have FireWire or IDE/SCSI sockets on the motherboard to operate with front IDE/SCSI sockets??

IIRC it uses both the USB and SATA. I know there's a SATA connected, don't remember if there's a USB connected but I think there is. I did not use the firewire interface....everything works. I think you can use one or the other between the USB and firewire.

I acquired another machine that had a Tableau T3458is Forensic Bridge in it.... These are fabulous for data recovery; especially this model, it has interfaces for non-standard things these days; such as IDE & SCSI. I don't get many recovery requests from SCSI stuff anymore, but I still get quite a few in here with old non-functioning systems with IDE HDD's in them that they want the data recovered from. The forensic bridge makes it a lot easier & faster! ...and here we go!!

Depends on the workload and just how much stuff needs to be tested. Not uncommon to bake things in it all night if testing excessively large amounts of RAM or slow stuff.....and of course for longevity testing. If needing to see how well things can handle heat; for example something that'll be in a harsher environment in the real world. I'll run them for hours with the exhaust fans turned down very low or off. Found lots of weird testing derivatives that proven to be quite useful.

So another words you torture test devices interesting I will have to remember that you have the ability and the tools to do this type of testing

[Topcat]

Are you torching your testing machine it was not that long ago that you put this machine together how much do you run it in a week

The official 1000 hour update.... I ran a board this morning and checked on it a few minutes ago....clock is at 1004.4. Nothing to report other than one more digit rolled from zero to one!

Probably just write it off as a grouchy motherboard.

I would agree with you as long as you do not run into this issue again but with a different brand motherboard that requires a lot of current on the 3.3 volt rail or maybe find a switching power supply that can handle more current on the 3 volt rail as an option

I can see the benefits this jig that you made to test motherboard and it supporting components this a perfect example of how this setup gives you the ability and the data that is needed and required to be able to troubleshoot an issue easily this is one reason I followed this post very closely and read what you have said about the requirements that you had when building it

[Topcat]

What type of switching power supply did it originally come with look at the specs on the 3.3 volt rail and this might enlighten you what might be going on and it might also be the supervisor ic chip not liking the fact that 3.3 volt is load more than the 5 volt power supply rail it might be 12 volt rail as well <— this is just a guess to what might be going on

It's an Emac 550W redundant server supply with a 3.3v rail rated @ 24A. I forget the model number. I haven't been able to replicate the issue with any other 3.3v heavy board I have here... Probably just write it off as a grouchy motherboard.

Could it be that there's interference getting into the +3.3V rail through all of the accessory wiring and gadgets in the box? How do the rails look under load on an analog oscilloscope with a motherboard in it that flakes out?

Clean enough, I looked. It wasn't a perfect flatline, there was a 14A load on it....but I've seen stable systems with far more noise. Hard to believe the rail would have been falsely rated given the maker of the unit; but that's the heaviest I've ever yanked on the 3.3v rail...voltage held true, never fluctuated/dropped beyond .2v under loads. Low/no load it's solid at 3.4v. At the highest load it was 3.2v.

Nothing modern really ever touches this rail anymore; I did have an Asus Westmere LGA1366 pull hard on the 3.3v rail, but this board was completely stable in the oven inspite the load. Just wondering if it was just a board being stubborn....I'm out of answers really. It was only this model board (P4DCE+) that ever created this issue; a matching pair of them, both did it.

[TechGeek]

The 1000 hour update (932.6 to be exact)....and one weird bug to report. This has occurred with 2 boards of the several hundred that have baked in the oven. Two identical boards that are extremely heavy on the 3.3v rail have created false memory failure errors with software (memtest). The 3.3v rail of the TPU is rated at 24A. These boards create a constant ~13A+ load on the 3.3v rail with bounces as high as ~17A; very few & far between... This isn't really a factor for anything, especially anything modern, both of these boards were netburst era Xeons; Supermicro P4DCE+ (RDRAM) to be exact. Two identical boards that created this and when retested on another power supply they tested fine; memory passed... I knew the memory was good to begin with, which is what made me suspicious... I've tested plenty of 3.3v heavy boards without issue, although these two here the highest I've ever seen pulling from the 3.3v rail.... I don't plan on any corrective action for this, as it's not really a factor for anything. I'm not sure what's even causing it. These boards pulled nothing from the 5v rail and lightly from the +12v rail..

Update

I got another motherboard and I now have it up and running now with it being reimagined to the factory settings and the recovery partition on a HP Elite 8200 CMT with the Tableau UltraBay 3D interface duplicator with the LCD screen display and the USB controller board installed with the locking tab in place so the board does not move in the PCI slot installed in HP computer case

Now the motherboard that got fried I going to remove the power cord connectors to the motherboard to power the CD rom drive and the hard drive to also power the Tableau UltraBay 3D interface so I use it correctly and not have it jerry rigged like I had it to test it weather or not the Tableau UltraBay 3D interface with the LCD screen display device worked or not now that I know it works it is time to do it the right way

When I have it up and running correctly I will start a new post about this device and how I am going to be using it
